In the words of philosopher and poet George Santayana, “Those who cannot remember the past are condemned to repeat it.” But this time around, we beg to differ! We agree that advice from the early 1900s is not the first place you go for hacks to make life simpler. (Thanks, Google!) However, the New York Public Library digitized 100 “How to Do It” cards that manufacturers would place inside cigarette boxes.

Back in the early twentieth century, cigarette companies would place these cards in their products. They quickly became collectibles that included anything from celebrity photos to advertisements. But printing life hacks on these cards was an idea pioneered by the UK-founded tobacco company Gallaher cigarettes. Now, while we can’t support cigarettes themselves, there is no doubting these cigarette card life hacks probably helped make many people’s lives easier, at least a little bit.

For your viewing pleasure, we’ve compiled a list of the most clever and practical 100-year-old life hacks that are still useful today.
